[nem-en] Bugs in extension method implementation

[Kamil Skalski]

Hm, get following results trying to reproduce this from command line:

nazgul at mordor ~/nemerle/ncc/testsuite
$ ../../boot/ncc.exe -r ../out.stage3/Nemerle.Compiler.dll
../testsuite/t.n  -greedy-

debug: loaded extension attribute from assembly Nemerle,
Version=0.9.3.26, Culture=neutral, PublicKeyToken=e080a9c724e2bfcd adn
type Nemerle.Internal.ExtensionAttribute
../testsuite/t.n:5:13:5:27: error: there is no member named `GetName'
in Nemerle.Compiler.IMember with type ?

nazgul at mordor ~/nemerle/ncc/testsuite
$ ../../boot/ncc.exe -r mscorlib -r ../out.stage3/Nemerle.dll -r
../out.stage3/Nemerle.Compiler.dll ../testsuite/t.n -no-stdlib
-greedy-

debug: loaded extension attribute from assembly Nemerle,
Version=0.9.3.24, Culture=neutral, PublicKeyToken=e080a9c724e2bfcd adn
type Nemerle.Internal.ExtensionAttribute


This is different from your results - your output looks like VS would
compile without "no-stdlib" flag. The strange thing is that I can't
see "-greedy-" flag in your output, but without it I get the error:

nazgul at mordor ~/nemerle/ncc/testsuite
$ ../../boot/ncc.exe -r mscorlib -r ../out.stage3/Nemerle.dll -r
../out.stage3/Nemerle.Compiler.dll ../testsuite/t.n -no-stdlib

debug: loaded extension attribute from assembly Nemerle,
Version=0.9.3.24, Culture=neutral, PublicKeyToken=e080a9c724e2bfcd adn
type Nemerle.Internal.ExtensionAttribute
error: internal compiler error: got some unknown exception of type
System.IO.FileLoadException: Could not load file or assembly 'Nemerle,
Version=0.9.3.24, Culture=neutral, PublicKeyToken=e080a9c724e2bfcd' or
one of its dependencies. The located assembly's manifest definition
does not match the assembly reference. (Exception from HRESULT:
0x80131040)
